It took me quite a while to finish reading this book. More than a month actually. It's not a hard book to read, if one is judging it purely based on grammar, sentence structure, and progression.
The writing was quite simple, but the details lead my mind to think and wander. While reading 2666, I, being an overly analytical person, was already going ahead of myself and forming my own conclusions. Thoughts, that because the writing was too detailed and extended, became more of a distraction. Picture 2 different songs played simultaneously, one slow and monotonous and the other fast and syncopated. What do you get? Noise. Yes, my friends. I read 2666 for more than a month because I suffered from "brain noise".
